SPENCER XV. I-IU'ICHISON, OF OAKLAND, CALIFORNIA.

COMBINATION COMPASS AND CHRONOMETER.

Application filed August 27, 1923. Serial No. 659,603.

T 0 all whom it may concern:

Be it known that I, SPENCER V. HU'ronrson, a citizen of the United States, residing in the city of Oakland, and county of Ala meda, and State of California, have invented a new and useful Improvement in a Combination Compass and Chronometer, of which the following is a specification.

My invention relates to improvements in a combined compass and chronometer wherein a compass needle is mounted upon the post of a watch or other chronometer and arranged for free movement independcntly of the pointers of the chronometer for indicating direction upon the dial of the chronometer.

The primary object is to provide a device adapted to indicate both time and direction.

Another object is to provide a device wherein the dial of an ordinary watch or the like is utilized in connection with a compass needle for indicating direction as well as time.

A further object is to provide an improved construction and arrangement adapted to permit the mounting of a compass needle adjacent the dial and pointers of a chronometer without interfering with the normal operation of the chronometer in indicating time.

I accomplish these and other objects by means of the improved device disclosed in the drawings forming a part of the present specification wherein like characters of reference are used to indicate similar parts throughout said specification and drawings and in which,

Fig. 1 is afront elevation of my improved compass and chronometer. V

Fig. 2 is an enlarged end elevation of the device as shown in Fig. 1, parts being broken away and shown in section to illustrate the construction and anrangement of parts.

Fig. 8 is an enlarged sectional detail showing the manner in which the needle is mounted upon the post independently of the time indicating pointers.

Referring to the drawings the numeral 1 is used to designate in general a watch or other chronometer provided with a dial 2 having time indicating indices 3 arranged aroundcthe edge of the dial. The chronometer is provided wit-h the usual hour hand 4 and minute hand 6 mounted in common upon a centrally positioned post 7, said hands at and 6 being actuated in the well known manner as pointers operating in association with the time indices 3 for indicating time. dVatches and chronometers of the character mentioned are of such well known construction as to require no detailed description herein.

in my in'iproved device the central post 7 upon which the pointers dand 6 are mounted is provided with an outwardly extending pointed tip 8 upon which is mounted a compass needle 9. T he needle 9 is provided with a central bearing portion 11 preferably having a jewel bearing 12 arranged to seat upon the point of the tip 8 whereby the needle will rest in balanced condition and be freely movable above the pointers -l and 6 when the chronometer is held in a substantially level position. The ends of the needle 9 are bent inwardly toward the dial 2 at their extreme tips as at 13 and 1d, and tips being arranged to extend beyond the ends of the pointers a and 6 and to just clear the dial when the chronometer is held in level position, and to engage said dial and hold the needle in spaced relation to the pointers when the chronometer is tipped away from the level position, in this manner insuring clearance between the needle and the pointers and permitting both the needle and the pointers to operate independently without interfering with the normal operation of either.

indices 16 are arranged around the edge of thedial 2 adj accnt the indices 3, to indicate the points of compass. When the chronometer is held in level position, the needle 9 being freely movable upon the post 7 will swing to north and south position and the dial may thus be utilized in the well known manner for indicating direction. At

the same time the chronometer will continue to operate in the ordinary manner to in dicate time by means of the indices 8. By thus mounting the compass needle upon the central post of the chronometer and arranging it to operate in conjunction with the dial of the watch for indicating direction and the single case and dial thus utilized for both purposes. The usual crystal 17 is provided to enclose the needle and pointers in the well known manner said crystal being arranged to normally prevent the needle 9 from becoming unseated from the post- 7.

Having thus described my invention what I claim as new and desire to secure by Letters Patent is,
